What is the proof for God? Is there any conclusive proof of God?

TL;DR:

The Bible assumes God’s existence and does not seek to prove it. Various philosophical, logical, and scientific arguments offer solid evidence for the existence of a Creator.

Nowhere in the Bible are there arguments seeking to prove God's existence. The fact of His existence is assumed from the very first verse, "In the beginning God created the heavens and the earth" (Genesis 1:1). Instead of proving God's existence, the Bible calls upon people to make a venture of faith toward Him. It is impossible to know God except by faith (Hebrews 11:6).

While the Bible does not directly argue for God's existence, fulfilled prophecy does demonstrate God's existence as well as the divine inspiration of the Bible. The many Old Testament prophecies about the Messiah that Jesus Christ uniquely fulfilled tells us not only that God exists, but that He also controls the future.

Looking beyond the Bible, many logical, philosophical and scientific arguments have been developed that prove God's existence. Whether or not one accepts a proof as conclusive depends on whether or not that person accepts the evidence.

from the old testament

Only a fool says in his heart "There is no God" (Psalm 14:1).
The design and order of the natural world reveals the existence of God and His attributes (Psalm 19:1).
There is none like God - He knows the end from the beginning (Isaiah 46:9-10).

from the new testament

Jesus already existed with God before the beginning of the world (John 1:1-2).
God has made His existence plain for everyone to see. His eternal power and divine nature are clearly perceived from creation (Romans 1:19-20).
Whoever comes near to God must believe that God exists and that He rewards those who seek Him (Hebrews 11:6).

implications for today

Here are brief introductions to four classic arguments for believing in God. Some arguments are stronger than others, and depending on your background, you may find one more conclusive than the others.

First, there’s the cosmological case, often associated with Thomas Aquinas, that says everything that exists has a cause and so there must be a first cause (God).

Second is the teleological argument, which points to the complexity and order of the universe as evidence of an intelligent designer.

Third, there’s the moral argument, popularized by C. S. Lewis, that points to the existence of objective moral values and duties, which require a moral lawgiver.

Fourth is the ontological argument originated by St. Anselm, which is a philosophical argument that attempts to prove the existence of God through reasoning alone, without relying on empirical evidence.

As we reflect on these arguments, we are invited to consider how they might shape our understanding of God's existence and His role in the world. We are called to recognize the evidence of a Creator in the world around us and to respond by faith to Him, trusting that He is the source of all life, meaning, and purpose. How will we respond to the Creator who has revealed Himself through creation, morality, and reason?

understand

The Bible assumes God's existence and calls for faith rather than proving it.
Fulfilled prophecy and the natural world provide evidence of God's existence and control over the future.
Philosophical, logical, and scientific arguments (like the cosmological, teleological, moral, and ontological arguments) offer solid evidence for the existence of a Creator.

reflect

How does the Bible's assumption of God's existence challenge the way you approach Him?
What roles have faith and reason played in your understanding of God's existence?
How do you personally recognize God’s presence in the world around you?

engage

How do the different arguments for God's existence (cosmological, teleological, moral, ontological) complement each other, and how can we use these proofs when talking to those who are skeptical of God’s existence?
How does faith work with empirical evidence in seeing proof of God?
How might reflecting on fulfilled prophecy deepen our trust in God's existence and His control over history?
